Since the natural place to clear both ->dl_yielded and ->dl_throttled is in replenish_dl_entity(); both are after all waiting for that event; make it so. Luckily since 67dfa1b756f2 ("sched/deadline: Implement cancel_dl_timer() to use in switched_from_dl()") the task_on_rq_queued() condition in dl_task_timer() must be true, and can therefore call enqueue_task_dl() unconditionally.
